SNL 40th Anniversary: The A-List Party of the Season!

Sure the windchill in NYC dropped to an unbearable -9 degrees and New York Fashion Week was in full roar, but some of Tinseltown's boldest face celebs stepped out anyway for Saturday Night Live's 40th Anniversary fete (which took place last night-- a Sunday!)

The comedy sketch show drew all the ol' SNL regulars like Tina Fey, Jimmy Fallon, Eddie Murphy, Alec Baldwin, Rachel Dratch, Seth Meyers, Amy Poehler, Steve Martin and Maya Rudolph (who did a hilarious Beyoncé impersonation on stage), and plenty of other funny guys and gals like Larry David, Jerry Seinfeld, Kristen Wiig and Chris Rock. But as with the best kinds of parties, it was a mixed crowd. Justin Timberlake took Instagrams from backstage.

The red carpet was also sprinkled with plenty of glamorous ingenues with ready laughs (and there were plenty of them to be had). Emma Stone, who has comedic chops of her own playing Roseanne onstage, shared a few grins with Larry David while walking the carpet in a black sequined Christian Dior number. Dakota Johnson also chose sequins although in metallic shades by Sonia Rykiel. The sisters trio Haim, dressed in pieces by Givenchy and Acne, were particularly excited about a possible Mary Catherine Gallagher sighting. They were on the heels of bestie Taylor Swift, who wowed in an Azzaro dress with cut-outs. The friends actually had just spent Saturday night together too. Hanging with Taylor is "the craziest amount of fun I think we've ever had," they told InStyle. "We ate a lot of chocolate chip cookies last night that she baked for Valentine's Day and they were delicious. I just sat there and watched her bake until I could down them." Funny and sweet.
